CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 622,360, dated. April' 4, 1899.

Application'filed January 23, 1899.` Serial No. 703,098. (No model.)

for wedging the door tightly against the frame when closed, the wedging device being released as the door is moved in opening, so as to permit its carrying-wheels to run freely on their track and allow the door to swing out of frictional contact with the side of the carbody. These objects are attained by the construction hereinafter fully described and which is illustrated in the accompanyingv drawings, in which- Figure 1 is a detail vertical section of the side of a car and of the door. Fig. 2 is a detail section on the line 2 2 of Fig. 1. Fig. 3 is a detail on the line 3 3 of Fig. l.' Fig. 4 is a detail 0f an element of the Wedging device, and Fig. 5 is-adetail section similar to that shown in Fig. l and representingmodifications in the construction.

In all of the gures some of the parts are shown in elevation.

A portion of the side Wall of the car-body is represented at A, of one of the upright-s of the door-frame at B, ofthe facia at b, and of the door at C. The door is shown as double-that is to say, made of two I(hicknesses of material-and the outer one is cut away across the top, giving the upper edge of the door the form of a rabbet. Within the angle of this rabbet there is set a triangular fillet c for the purpose of shedding water.

The hangers D may be of any desired form and are secured and bolted to the door, as

shown, projecting upwardly and being provided with suitable wheels or rollers el, whichv which it is secured to the side of the car, and

at its outer edge a pendent flange e, which overhangs the door. The inner face of the flange e is provided with aboss F, one end of which is beveled. y This boss may be formed in any desired manner. As shown and preferred, it consists of a small casting riveted to the flange. A corresponding block G, having one of its ends beveled, rests against the upright Wall of the rabbet at the upper edge of the door and coperates with the boss F, the fillet c being cut away to accommodate it. The boss F and block G are so disposed that they come into engagement when the door is closed and are disengaged as soon as the door moves in opening. The effect of their joint action is to throw the door tightly against the casing, thereby preventing the admission of dust and obviating the rattling of the door and facilitating its proper fastening. The parts F and Gr are preferably, though not necessarily, located under the door-hangers, a pair being used in connection with each hanger.

Preferably the block G is formed integrally with the hanger D, being connected therewith by means of a stem or arm g, as plainly shown in Figs. l and et; but, if desired, it may be bolted or riveted directly to the body of the door, as shown in Fig. 5.

The track-rail E need not necessarily be 0f Z- form; but preferably itsV tread portion 'should be smooth-Ji. e., without either rib or groove--so that the wheels or rollers d may be allowed some lateral play. Vhen a tracksupport h is secured to the side of the car, as shown in Fig. 5, the track-rail I-Imay com'- prise a simple angle-bar, one flange of which rests upon the top of the support 7L, the other fiange depending and overhanging the door.
